Sioux Chief PowerPEX® 630WG Series 630WG2138 Standard Stubout Elbow, 1/2 in PEX x PEX, Copper

The Sioux Chief PowerPEX® ASTM F1960 fitting system has a larger ID, which provides higher flow rates than other insert-fitting systems. Expansion tools are used to expand the tube and F1960 PEX rings, which then shrink to compress over fitting barbs. All expansion joints made using PowerPEX Type-B tubing MUST be made with a self- rotating, power expansion tool to eliminate weak spots and avoid improper expansion rates.
